Description

顯示裝置及其驅動方法Display device and driving method thereof

本揭露係關於一種顯示裝置及其驅動方法，包含一種顯示裝置，其中觸控感測器被嵌於顯示面板中且包含觸控敏感元件從而為使用者提供觸控識別與觸覺回饋（feedback）以回應觸控輸入。The present disclosure relates to a display device and a driving method thereof, including a display device in which a touch sensor is embedded in a display panel and includes a touch sensitive element so as to provide a user with touch recognition and tactile feedback to Respond to touch input.

觸控感測器為偵測使用者之觸控輸入之裝置，比如用於顯示裝置或手勢（gesture）之螢幕觸控。這些被廣泛用於大尺寸顯示裝置的公共設備中的觸控感測器顯示裝置中，比如智慧電視等以及可攜式顯示裝置比如智慧電話、輸入板個人電腦等。The touch sensor is a device that detects a user's touch input, such as a screen touch for a display device or a gesture. These are widely used in touch sensor display devices in public devices of large-sized display devices, such as smart TVs, and portable display devices such as smart phones, tablet personal computers, and the like.

根據觸控感測器在顯示面板中的放置位置將觸控感測器分類。舉個例子，觸控感測器被分類為內嵌式（in-cell type）觸控感測器、外嵌式（on-cell type）觸控感測器、附加式（add-on type）觸控感測器與混合式（hybrid type）觸控感測器。在內嵌式觸控感測器中，觸控感測器被嵌入顯示面板中。在外嵌式觸控感測器中，觸控感測器形成於顯示面板之頂部上。在附加式觸控感測器中，單獨製造的觸控感測器被單獨放置於顯示裝置之頂部上。在混合式觸控感測器中，組合了各種類型的觸控感測器。各種類型的觸控感測器中，因為單獨的觸控感測器需要被接合至顯示裝置的頂部，附加式增加了顯示裝置的厚度與相應的製造成本，由此不期望這種類型的觸控感測器。另外，難以將附加式觸控感測器接合至撓性顯示裝置。因此，近年來，利用內嵌式觸控感測器將觸控感測器整合至顯示面板中的興趣已經日益增加，或者已經連續地製造附加式觸控感測器從而提供輕薄的顯示裝置。The touch sensors are classified according to the position where the touch sensors are placed in the display panel. For example, touch sensors are classified as in-cell type touch sensors, on-cell type touch sensors, and add-on types Touch sensors and hybrid type touch sensors. In the in-cell touch sensor, the touch sensor is embedded in the display panel. In the in-cell touch sensor, the touch sensor is formed on the top of the display panel. In the additional touch sensor, a separately manufactured touch sensor is separately placed on the top of the display device. In the hybrid touch sensor, various types of touch sensors are combined. Among the various types of touch sensors, since a separate touch sensor needs to be bonded to the top of the display device, the additional type increases the thickness of the display device and the corresponding manufacturing cost, so this type of touch sensor is not expected. Control sensor. In addition, it is difficult to attach an additional touch sensor to a flexible display device. Therefore, in recent years, there has been an increasing interest in integrating touch sensors into display panels using in-cell touch sensors, or additional touch sensors have been continuously manufactured to provide thin and light display devices.

近年來，對觸覺裝置的興趣也日益增加，觸覺裝置不僅偵測使用者之觸控輸入還將利用手指或觸控筆（stylus pen）感受到的觸覺回饋傳送，以通知使用者已收到使用者的觸控輸入。In recent years, interest in haptic devices has also increased. Not only does the haptic device detect the user's touch input, but it also uses the tactile feedback sent by a finger or stylus pen to notify the user that the device has been received. Touch input.

各種觸覺裝置中，已經使用採用了偏心旋轉質量（eccentric rotating mass；ERM）、線性共振致動器（linear resonant actuator；LRA）、壓電陶瓷致動器（piezo ceramic actuator）等的觸覺裝置。然而，通常觸覺裝置由不透明的材料製成，振動顯示裝置的整體而非特定部分，無法提供不同的振動，以及由於耐受性低容易被外部衝擊破壞。Among various haptic devices, haptic devices using eccentric rotating mass (ERM), linear resonant actuator (LRA), piezo ceramic actuator, etc. have been used. However, in general, the haptic device is made of an opaque material, and the whole of the display device, rather than a specific part, cannot provide different vibrations, and is easily damaged by external impact due to low resistance.

因此，對發展觸覺裝置的興趣日益增加，以解決其中整合觸控感測器之顯示裝置相關的上述問題。Therefore, there is an increasing interest in developing haptic devices to solve the above-mentioned problems related to display devices in which touch sensors are integrated.

本揭露之代表性目的在於提供一種顯示裝置及其驅動方法，可傳送觸控感測且提供觸覺回饋，從而解決觸控敏感元件中產生的雜訊所導致的觸控輸入的錯誤識別問題。A representative object of the present disclosure is to provide a display device and a driving method thereof, which can transmit touch sensing and provide tactile feedback, thereby solving the problem of misrecognition of touch input caused by noise generated in the touch sensitive element.

The common electrode 123 is electrically connected to a common voltage line to receive a common voltage, and the pixel electrode is electrically connected to a thin film transistor to receive a data voltage. For ease of description, the pixel electrodes are not shown in FIG. 1, but according to the adjustment method of the array of the liquid crystal layers 140 of the display panel 170, the pixel electrodes may be formed at different positions. For example, when the display panel 170 is a liquid crystal display panel in an in-plane switching (IPS) mode, the pixel electrodes and the common electrode 123 are alternately arranged in parallel on the same plane to generate the pixel electrode and the common electrode 123. The horizontal electric field between the electrodes 123. Alternatively, when the display panel 170 is a liquid crystal display panel in fringe field switching (FFS) mode, the pixel electrode and the common electrode 123 are spaced apart from each other, and an insulating layer is placed between the two to generate a pixel electrode. A vertical electric field with the common electrode 123.

液晶層140被放置於共同電極123上。隨著資料電壓與共同電壓分別被提供至畫素電極與共同電極123，產生的電場改變液晶層140之液晶陣列。基於上述方法調整的液晶的方向，透過調整背光單元照射的光線的透射率，顯示面板170顯示影像。The liquid crystal layer 140 is placed on the common electrode 123. As the data voltage and the common voltage are supplied to the pixel electrode and the common electrode 123, respectively, the generated electric field changes the liquid crystal array of the liquid crystal layer 140. Based on the orientation of the liquid crystal adjusted by the above method, the display panel 170 displays an image by adjusting the transmittance of the light radiated by the backlight unit.

第二基板114被放置於液晶層140上，彩色濾光片151與黑色矩陣152被放置於第二基板114與液晶層140之間。第二基板114支撐如彩色濾光片151與黑色矩陣152等在第二基板114上形成的各種部件。第二基板114被放置為面對第一基板111，以及由撓性玻璃或塑膠製成。彩色濾光片151例如由紅色彩色濾光片、綠色彩色濾光片與藍色彩色濾光片構成，用以將穿透液晶層140的光線轉換為具有特定顏色的光線。彩色濾光片151與黑色矩陣152被放置於第二基板114上，如圖1所示，但是本揭露並非限制於此，彩色濾光片151與黑色矩陣152可以被放置於第一基板111上。The second substrate 114 is placed on the liquid crystal layer 140, and the color filter 151 and the black matrix 152 are placed between the second substrate 114 and the liquid crystal layer 140. The second substrate 114 supports various components formed on the second substrate 114 such as the color filter 151 and the black matrix 152. The second substrate 114 is placed to face the first substrate 111 and is made of flexible glass or plastic. The color filter 151 is composed of, for example, a red color filter, a green color filter, and a blue color filter, and is configured to convert light passing through the liquid crystal layer 140 into light having a specific color. The color filter 151 and the black matrix 152 are placed on the second substrate 114, as shown in FIG. 1, but the disclosure is not limited thereto.

觸控感測器為與顯示面板170整合的內嵌式觸控感測器。就是說，觸控感測器被放置於顯示面板170中。觸控感測器包含複數個觸控電極130。這種情況下，複數個觸控電極130還用作共同電極123，即一個電極可作業為共同電極123與觸控電極130。因此，顯示面板170被時分驅動，在影像顯示週期期間，藉由被施加至共同電極123的共同電壓（影像顯示訊號）透過畫素電極與共同電極123之間形成的電場顯示影像，以及在觸控感測週期期間，觸控訊號被施加至共同電極123，就是說，觸控電極130偵測來自使用者的觸控輸入。The touch sensor is an in-cell touch sensor integrated with the display panel 170. That is, the touch sensor is placed in the display panel 170. The touch sensor includes a plurality of touch electrodes 130. In this case, the plurality of touch electrodes 130 are also used as the common electrode 123, that is, one electrode can operate as the common electrode 123 and the touch electrode 130. Therefore, the display panel 170 is time-division-driven. During an image display cycle, a common voltage (image display signal) applied to the common electrode 123 displays an image through an electric field formed between the pixel electrode and the common electrode 123, and the During the touch sensing period, a touch signal is applied to the common electrode 123, that is, the touch electrode 130 detects a touch input from a user.

上述顯示面板170中，內嵌式觸控感測器中出現觸控電極130與閘極線121間的電容、觸控電極130與資料線122間的電容、觸控電極130與畫素電極間的電容，以及彼此鄰接的觸控電極間的電容。當使用者利用手指完成觸控輸入時，除了上述電容分量以外，觸控電極130與使用者的手指間也產生電容，觸控電極130中的電容變化。因此，當觸控訊號被施加至觸控電極130時，根據上述電容中的變化，透過感測訊號變動，偵測是否出現觸控與觸控輸入位置。將結合圖3詳細描述透過內嵌式觸控感測器用以偵測使用者之觸控輸入之顯示面板170之驅動方法。In the above display panel 170, the capacitance between the touch electrode 130 and the gate line 121, the capacitance between the touch electrode 130 and the data line 122, and the capacitance between the touch electrode 130 and the pixel electrode appear in the in-cell touch sensor. And the capacitance between adjacent touch electrodes. When a user uses a finger to complete a touch input, in addition to the capacitance component described above, a capacitance is also generated between the touch electrode 130 and the user's finger, and the capacitance in the touch electrode 130 changes. Therefore, when a touch signal is applied to the touch electrode 130, it is detected whether a touch and a touch input position occur by sensing the signal change according to the change in the capacitance. A driving method of the display panel 170 for detecting a user's touch input through the in-cell touch sensor will be described in detail with reference to FIG. 3.

進一步如圖1所示，觸控敏感元件160被放置於顯示面板170與觸控感測器上。觸控敏感元件160透過第一黏合層115與顯示面板170之第二基板114黏合，以及透過第二黏合層116與觸控敏感元件160上的蓋窗110黏合。蓋窗110由透明玻璃或透明塑膠製成，從而保護顯示裝置100避免外部衝擊等。第一黏合層115與第二黏合層116由透明黏合材料比如光學透明膠（optical clear adhesive；OCA）或光學透明樹脂（optical clear resin；OCR）製成，但是並非限制於此。As further shown in FIG. 1, the touch sensitive element 160 is placed on the display panel 170 and the touch sensor. The touch-sensitive element 160 is adhered to the second substrate 114 of the display panel 170 through the first adhesive layer 115, and is adhered to the cover window 110 on the touch-sensitive element 160 through the second adhesive layer 116. The cover window 110 is made of transparent glass or transparent plastic, thereby protecting the display device 100 from external impact and the like. The first adhesive layer 115 and the second adhesive layer 116 are made of a transparent adhesive material such as an optical clear adhesive (OCA) or an optical clear resin (OCR), but it is not limited thereto.

觸控敏感元件160具有電活性層163，以及放置於電活性層163的頂部表面與底部表面上的複數個電極。本揭露中，觸控敏感元件160為將觸覺回饋傳送至使用者的元件，以回應使用者對觸控敏感元件160的觸控，以及電活性層163係為在施加電壓時為形狀可變形的層，將產生的振動作為觸覺回饋傳送至使用者。The touch sensitive element 160 has an electroactive layer 163 and a plurality of electrodes placed on the top surface and the bottom surface of the electroactive layer 163. In this disclosure, the touch-sensitive element 160 is an element that transmits tactile feedback to the user in response to the user's touch on the touch-sensitive element 160, and the electroactive layer 163 is deformable in shape when a voltage is applied Layer, transmitting the generated vibration to the user as a tactile feedback.

電活性層163為電活性聚合物製成的板式膜，係為電刺激變形的聚合物材料。舉個例子，電活性層163由比如矽基、胺甲酸乙酯基（urethane base）與丙烯酸基之介電彈性體、比如聚偏二氟乙烯（polyvinylidene fluoride；PVDF）與聚二氟亞乙烯－三氟乙烯聚合物（poly(vinylidenefluoride-co-trifluoroethylene)；P(VDF-TrFE)）之鐵電性聚合物，或壓電陶瓷元件製成。當電活性層163由介電彈性體製成時，由於施加至電活性層163的電壓產生的靜電吸引（庫侖引力），介電彈性體收縮與膨脹，從而振動觸控敏感元件160。或者，當電活性層163由鐵電性聚合物製成時，透過施加電壓至電活性層163，電活性層163中偶極的定向方向改變，從而振動觸控敏感元件160。The electroactive layer 163 is a plate film made of an electroactive polymer, and is a polymer material deformed by electrical stimulation. For example, the electroactive layer 163 is made of a dielectric elastomer such as silicon, urethane base, and acrylic, such as polyvinylidene fluoride (PVDF) and polyvinylidene fluoride— Trifluoroethylene polymer (poly (vinylidenefluoride-co-trifluoroethylene); P (VDF-TrFE)) ferroelectric polymer or piezoelectric ceramic element. When the electroactive layer 163 is made of a dielectric elastomer, due to the electrostatic attraction (Coulomb's gravity) generated by the voltage applied to the electroactive layer 163, the dielectric elastomer contracts and expands, thereby vibrating the touch-sensitive element 160. Alternatively, when the electroactive layer 163 is made of a ferroelectric polymer, by applying a voltage to the electroactive layer 163, the orientation direction of the dipoles in the electroactive layer 163 changes, thereby vibrating the touch sensitive element 160.

複數個第一電極161被放置於電活性層163的頂部表面上，以及複數個第二電極162被放置於電活性層163的底部表面上。The plurality of first electrodes 161 are placed on the top surface of the electroactive layer 163, and the plurality of second electrodes 162 are placed on the bottom surface of the electroactive layer 163.

複數個第一電極161與複數個第二電極162由導電材料製成。另外，為了確保觸控敏感元件160的透射率，第一電極161與第二電極162由透明導電材料比如氧化銦錫（indium tin oxide；ITO）、聚二氧乙基塞吩:聚苯乙烯磺酸（PEDOT:PSS）以及銀奈米線（silver-nanowire；AgNW）製成。另外，第一電極161與第二電極162可以為金屬網格，其中金屬材料被放置為網格圖案，這樣第一電極161與第二電極162實質上用作透明電極。然而，第一電極161與第二電極162的組成材料並非限制於上述例子，可以使用各種其他的透明導電材料。第一電極161與第二電極162可以由相同材料或不同材料製成。The plurality of first electrodes 161 and the plurality of second electrodes 162 are made of a conductive material. In addition, in order to ensure the transmittance of the touch sensitive element 160, the first electrode 161 and the second electrode 162 are made of a transparent conductive material such as indium tin oxide (ITO), polydioxetine: polystyrene sulfonate Acid (PEDOT: PSS) and silver-nanowire (AgNW). In addition, the first electrode 161 and the second electrode 162 may be a metal grid, in which a metal material is placed in a grid pattern, so that the first electrode 161 and the second electrode 162 are substantially used as transparent electrodes. However, the constituent materials of the first electrode 161 and the second electrode 162 are not limited to the above examples, and various other transparent conductive materials may be used. The first electrode 161 and the second electrode 162 may be made of the same material or different materials.

透過包含濺射、列印、狹縫塗佈等各種方法形成第一電極161與第二電極162。The first electrode 161 and the second electrode 162 are formed by various methods including sputtering, printing, and slit coating.

如上所述，透過分別施加電壓至電活性層163之頂部表面與底部表面上放置的第一電極161與第二電極162而產生的電活性層163的振動，由電活性聚合物製成的觸控敏感元件160傳送觸覺回饋至使用者。另外，因為觸控敏感元件由透明材料製成，觸控敏感元件160具有高透射率，所以觸控敏感元件160被應用至顯示裝置100之前表面。As described above, the vibration of the electroactive layer 163 generated by applying a voltage to the first electrode 161 and the second electrode 162 placed on the top surface and the bottom surface of the electroactive layer 163, respectively, The control sensor 160 transmits tactile feedback to the user. In addition, since the touch-sensitive element is made of a transparent material and the touch-sensitive element 160 has a high transmittance, the touch-sensitive element 160 is applied to the front surface of the display device 100.

觸控敏感元件160之複數個第一電極161與第二電極162的每一個僅僅與複數個觸控電極130中的一個觸控電極130重疊。就是說，觸控敏感元件160之複數個電極161與162的一個電極僅僅與一個觸控電極130重疊。將結合圖2更加詳細地描述複數個觸控電極130與觸控敏感元件160之複數個電極161與162之間的關係。Each of the plurality of first electrodes 161 and the second electrode 162 of the touch sensitive element 160 overlaps only one of the plurality of touch electrodes 130. That is, one of the plurality of electrodes 161 and 162 of the touch-sensitive element 160 overlaps only one touch electrode 130. The relationship between the plurality of touch electrodes 130 and the plurality of electrodes 161 and 162 of the touch sensitive element 160 will be described in more detail in conjunction with FIG. 2.

圖2係為本揭露第一代表性實施例之顯示裝置之平面示意圖。圖2中，為了便於描述，圖中僅僅表示顯示裝置100之多個部件中的觸控敏感元件160、觸控電極130與第一基板111，以及從觸控敏感元件160之頂部僅僅看到觸控敏感元件160、觸控電極130與第一基板111之狀態。因此，相同區域中其下方放置的元件僅僅由參考標號表示。FIG. 2 is a schematic plan view of a display device according to a first exemplary embodiment of the disclosure. In FIG. 2, for convenience of description, the figure only shows the touch-sensitive element 160, the touch electrode 130, and the first substrate 111 among the multiple components of the display device 100, and only the touch is seen from the top of the touch-sensitive element 160. The state of the control sensitive element 160, the touch electrode 130 and the first substrate 111. Therefore, components placed below it in the same area are indicated only by reference numerals.

如圖2所示，觸控敏感元件160包含複數個單元（cell）CE，其中複數個單元CE的每一個中放置複數個電極161與162，這樣第一電極161被放置於電活性層163的頂部表面上，以及第二電極162被放置於電活性層163的底部表面上。一個單元CE中放置的第一電極161與第二電極162具有相同的尺寸。就是說，彼此面對的第一電極161的一個表面與第二電極162的一個表面具有相同的面積。本文中，單元CE係為傳送觸覺回饋至使用者之最小單元區域，以及多個單元CE可獨立地傳送觸覺回饋至使用者。隨著觸控敏感元件160針對使用者的觸控輸入傳送觸覺回饋，考慮出現使用者的觸控輸入的區域，判定作為最小單元區域之單元CE。這種情況下，因為出現使用者的觸控輸入的區域係依照平均入的手指尺寸被判定，所以電活性層163之單元CE的區域係基於平均入的手指尺寸被判定。然而，上述電活性層163之單元CE的區域是代表性的，電活性層163之單元CE的區域並非限制於上述例子。As shown in FIG. 2, the touch-sensitive element 160 includes a plurality of cells CE, wherein a plurality of electrodes 161 and 162 are placed in each of the plurality of cells CE, so that the first electrode 161 is placed on the electroactive layer 163 On the top surface, and the second electrode 162 is placed on the bottom surface of the electroactive layer 163. The first electrode 161 and the second electrode 162 placed in one cell CE have the same size. That is, one surface of the first electrode 161 and one surface of the second electrode 162 facing each other have the same area. Herein, the unit CE is the smallest unit area for transmitting haptic feedback to the user, and multiple units CE can independently transmit haptic feedback to the user. As the touch sensitive element 160 transmits tactile feedback to the user's touch input, considering the area where the user's touch input occurs, the unit CE that is the smallest unit area is determined. In this case, since the area where the user's touch input occurs is determined according to the average finger size, the area CE of the cell CE of the electroactive layer 163 is determined based on the average finger size. However, the region of the unit CE of the electroactive layer 163 is representative, and the region of the unit CE of the electroactive layer 163 is not limited to the above examples.

如圖1與圖2所示，放置於觸控敏感元件160之一個單元CE中的第一電極161與第二電極162僅僅與那個特定單元CE中的觸控電極130重疊。換言之，觸控敏感元件160之特定單元CE中放置的第一電極161與第二電極162未與鄰接單元之觸控電極130重疊。As shown in FIGS. 1 and 2, the first electrode 161 and the second electrode 162 placed in one unit CE of the touch-sensitive element 160 only overlap the touch electrodes 130 in that particular unit CE. In other words, the first electrode 161 and the second electrode 162 placed in the specific unit CE of the touch sensitive element 160 do not overlap the touch electrodes 130 of the adjacent unit.

進一步如圖1與圖2所示，複數個電極161與162的每一個的尺寸與複數個觸控電極130中對應的觸控電極130的尺寸相同。舉個例子，面對觸控電極130的第一電極161的一個表面及第二電極162之一個表面與面對第一電極161及第二電極162的單元CE中的觸控電極130的一個表面具有相同的面積。因此，一個單元CE中放置的第一電極161與第二電極162的每一個一一對應觸控電極130。As further shown in FIG. 1 and FIG. 2, the size of each of the plurality of electrodes 161 and 162 is the same as the size of the corresponding touch electrode 130 in the plurality of touch electrodes 130. For example, one surface of the first electrode 161 and one surface of the second electrode 162 facing the touch electrode 130 and one surface of the touch electrode 130 in the unit CE facing the first electrode 161 and the second electrode 162 Have the same area. Therefore, each of the first electrode 161 and the second electrode 162 placed in one unit CE corresponds to the touch electrode 130.

觸控敏感元件160的複數個單元CE中的每一個包含由主動矩陣方法實施的驅動電路。當由被動矩陣方法實施觸控敏感元件160時，電極161與162具有條狀。這種情況下，觸控敏感元件160之第一電極161與第二電極162的每一個需要被放置為與複數個觸控電極130重疊。因此，本揭露第一代表性實施例之顯示裝置100之觸控敏感元件160之複數個單元CE中的每一個係基於主動矩陣方法被驅動。舉個例子，薄膜電晶體被放置於每一單元中作為驅動電路，以及薄膜電晶體施加觸控敏感元件驅動訊號至每一單元CE中放置的第一電極161與第二電極162。Each of the plurality of cells CE of the touch-sensitive element 160 includes a driving circuit implemented by an active matrix method. When the touch-sensitive element 160 is implemented by the passive matrix method, the electrodes 161 and 162 have a stripe shape. In this case, each of the first electrode 161 and the second electrode 162 of the touch-sensitive element 160 needs to be placed so as to overlap the plurality of touch electrodes 130. Therefore, each of the plurality of cells CE of the touch-sensitive element 160 of the display device 100 of the first exemplary embodiment of the present disclosure is driven based on an active matrix method. For example, the thin film transistor is placed in each unit as a driving circuit, and the thin film transistor applies a touch-sensitive element driving signal to the first electrode 161 and the second electrode 162 placed in each unit CE.

當觸控敏感元件160的第一電極161或第二電極162到處與複數個觸控電極130重疊時，不能準確地偵測使用者的觸控輸入。舉個例子，當觸控敏感元件160的第一電極161或第二電極162與彼此鄰接的兩個觸控電極130重疊時，使用者觸碰與兩個觸控電極130之一個觸控電極130所對應的位置，因為上述重疊的緣故，所以改變觸控電極130與第一電極161或第二電極162之間的電容。就是說，僅僅當使用者觸碰的單個觸控電極130的電容改變時，可準確地偵測到使用者的觸控輸入。When the first electrode 161 or the second electrode 162 of the touch-sensitive element 160 overlaps with the plurality of touch electrodes 130 everywhere, the user's touch input cannot be accurately detected. For example, when the first electrode 161 or the second electrode 162 of the touch-sensitive element 160 overlaps two touch electrodes 130 adjacent to each other, the user touches one of the two touch electrodes 130 The corresponding position changes the capacitance between the touch electrode 130 and the first electrode 161 or the second electrode 162 because of the overlap. That is, the touch input of the user can be accurately detected only when the capacitance of the single touch electrode 130 touched by the user is changed.

本揭露第一代表性實施例之顯示裝置100中，觸控敏感元件160之複數個電極161與162的每一個僅僅與複數個觸控電極130中的一個觸控電極130重疊。因此，當使用者觸碰與一個觸控電極130對應的位置時，僅僅與對應的觸控電極130重疊的電極161與162間的電容被充電，與對應觸控電極130鄰接的另一觸控電極130的電容中沒有變化。或者，甚至如果另一鄰接的觸控電極130的電容變化，可忽略這個變化。因此，在顯示裝置100中，甚至當觸控感測器被放置於觸控敏感元件160下方時，可準確地偵測到使用者的觸控輸入，以及透過觸控敏感元件160獲得的觸覺回饋被傳送至使用者。In the display device 100 of the first exemplary embodiment of the present disclosure, each of the plurality of electrodes 161 and 162 of the touch sensitive element 160 overlaps only one of the plurality of touch electrodes 130. Therefore, when the user touches a position corresponding to one touch electrode 130, only the capacitance between the electrodes 161 and 162 overlapping with the corresponding touch electrode 130 is charged, and another touch adjacent to the corresponding touch electrode 130 is charged. There is no change in the capacitance of the electrode 130. Alternatively, even if the capacitance of another adjacent touch electrode 130 changes, this change can be ignored. Therefore, in the display device 100, even when the touch sensor is placed under the touch sensitive element 160, the user's touch input and the tactile feedback obtained through the touch sensitive element 160 can be accurately detected. Is sent to the user.

以下，將一同結合圖3描述包含上述電極佈局結構之顯示裝置100之驅動方法。Hereinafter, a driving method of the display device 100 including the electrode layout structure described above will be described in conjunction with FIG. 3.

圖3係為用於本揭露代表性實施例之顯示裝置之驅動方法之輸入訊號之波形圖。圖3表示每一影像顯示與觸控感測週期中的影像顯示訊號與觸控訊號以及觸控敏感元件驅動訊號之波形圖，其中影像顯示訊號與觸控訊號被施加至共同電極123與觸控電極130，以及觸控敏感元件驅動訊號被施加至觸控敏感元件160的複數個電極161與162。FIG. 3 is a waveform diagram of input signals used in a driving method of a display device according to a representative embodiment of the disclosure. FIG. 3 shows waveforms of the image display signal and the touch signal and the driving signal of the touch sensitive element in each image display and touch sensing cycle. The image display signal and the touch signal are applied to the common electrode 123 and the touch. The electrodes 130 and the touch-sensitive element driving signals are applied to the plurality of electrodes 161 and 162 of the touch-sensitive element 160.

本揭露第一代表性實施例之顯示裝置100中，內嵌式觸控感測器與顯示面板170整合。如上所述，顯示面板170之共同電極123用作觸控電極130。為此，顯示裝置100被時分驅動至影像顯示週期與觸控感測週期內。舉個例子，如圖3所示，在一個框週期中的影像顯示週期期間，用於顯示影像之影像顯示訊號被施加至共同電極123，在共同電極123與畫素電極之間產生電場，以及液晶層140的液晶的方向被電場改變，從而顯示影像。這種情況下，未施加觸控訊號且未完成觸控感測。在一個框週期中的觸控感測週期期間，觸控訊號被施加至觸控電極130。當出現使用者的觸控輸入且施加觸控訊號時，觸控電極130關於閘極線121、資料線122、畫素電極或者使用者的手指的電容被改變，以偵測是否已出現觸碰以及觸碰的位置。雖然圖3中表示了直流觸控訊號電壓，但是本揭露並非限制於此，以及交流觸控訊號電壓可被應用至共同電極123。另外，為了便於描述，雖然圖3中影像顯示週期與觸控感測週期表示為在一個框週期中具有相同的長度，但是觸控感測週期可以比影像顯示週期短。In the display device 100 of the first exemplary embodiment disclosed herein, the in-cell touch sensor is integrated with the display panel 170. As described above, the common electrode 123 of the display panel 170 is used as the touch electrode 130. For this reason, the display device 100 is time-divisionally driven into an image display period and a touch sensing period. For example, as shown in FIG. 3, during an image display period in a frame period, an image display signal for displaying an image is applied to the common electrode 123, an electric field is generated between the common electrode 123 and the pixel electrode, and The direction of the liquid crystal of the liquid crystal layer 140 is changed by an electric field, and an image is displayed. In this case, no touch signal is applied and touch sensing is not completed. During a touch sensing period in a frame period, a touch signal is applied to the touch electrodes 130. When a user's touch input occurs and a touch signal is applied, the capacitance of the touch electrode 130 with respect to the gate line 121, the data line 122, the pixel electrode or the user's finger is changed to detect whether a touch has occurred And where it touched. Although the DC touch signal voltage is shown in FIG. 3, the disclosure is not limited thereto, and the AC touch signal voltage can be applied to the common electrode 123. In addition, for ease of description, although the image display period and the touch sensing period in FIG. 3 are represented as having the same length in one frame period, the touch sensing period may be shorter than the image display period.

顯示裝置100還包含觸控敏感元件160，用於傳送觸覺回饋至使用者，以及內嵌式觸控感測器與顯示面板170整合。顯示裝置100中，觸控敏感元件160施加電壓至複數個電極161與162以產生電場，以及產生的電場被施加至電活性層163，電活性層163變形且振動以提供觸覺回饋至使用者。舉個例子，如圖1所示，當垂直電場被施加至接地的第一電極161與第二電極162間放置的電活性層163時，電活性層163振動以提供觸覺回饋至使用者。The display device 100 further includes a touch-sensitive element 160 for transmitting tactile feedback to the user, and the in-cell touch sensor is integrated with the display panel 170. In the display device 100, the touch-sensitive element 160 applies a voltage to the plurality of electrodes 161 and 162 to generate an electric field, and the generated electric field is applied to the electroactive layer 163, which deforms and vibrates to provide tactile feedback to the user. For example, as shown in FIG. 1, when a vertical electric field is applied to the electroactive layer 163 placed between the grounded first electrode 161 and the second electrode 162, the electroactive layer 163 vibrates to provide tactile feedback to the user.

其間，當出現使用者的觸控輸入且用於觸控敏感元件160之驅動電壓被施加至第一電極161與第二電極162時，使用者的觸控輸入導致的電容變化由觸控敏感元件160中斷。因此，顯示裝置100之觸控敏感元件160被時分驅動。如圖3所示，在一個框週期中的影像顯示週期期間，因為用於顯示影像的影像顯示訊號被施加至共同電極123，所以共同電極123未偵測到使用者的觸控輸入。因此，交流電壓或脈衝電壓被施加至觸控敏感元件160之第一電極161，觸控敏感元件160之第二電極162接地以振動電活性層163。因為在一個框週期中的觸控感測週期期間，觸控訊號被施加至觸控電極130，當在觸控感測週期中驅動觸控敏感元件160時，觸控感測器不會正常地偵測觸控輸入。因此，在觸控感測週期期間，觸控敏感元件160的複數個電極161與162浮動，以及觸控感測器從而準確地偵測到使用者的觸控輸入。Meanwhile, when a user's touch input occurs and a driving voltage for the touch-sensitive element 160 is applied to the first electrode 161 and the second electrode 162, the capacitance change caused by the user's touch input is caused by the touch-sensitive element 160 interrupts. Therefore, the touch sensitive element 160 of the display device 100 is driven by time division. As shown in FIG. 3, during the image display period in one frame period, since the image display signal for displaying an image is applied to the common electrode 123, the common electrode 123 does not detect a user's touch input. Therefore, an AC voltage or a pulse voltage is applied to the first electrode 161 of the touch sensitive element 160, and the second electrode 162 of the touch sensitive element 160 is grounded to vibrate the electroactive layer 163. Because the touch signal is applied to the touch electrode 130 during the touch sensing period in a frame period, the touch sensor may not operate normally when the touch sensitive element 160 is driven in the touch sensing period. Detect touch input. Therefore, during the touch sensing period, the plurality of electrodes 161 and 162 of the touch sensitive element 160 float, and the touch sensor accurately detects the user's touch input.

顯示裝置100中，觸控感測器被嵌入顯示面板170中的嵌入式觸控感測器被應用，透過減少包含觸控感測器之顯示裝置100的厚度以提供輕薄的顯示裝置100。詳細地，單獨製造的觸控感測器未被放置於嵌入式觸控感測器中的顯示面板上，但是觸控感測器被放置於顯示面板中。因此，顯示裝置100具有小厚度，以及可製造為低成本。另外，顯示裝置100中，觸控感測器被放置於觸控敏感元件160前方，從而移除傳送給使用者的振動被降低的阻尼現象。因此，因為依照較低的驅動電壓驅動觸控敏感元件，還改善了觸控敏感元件160的功率消耗。In the display device 100, an embedded touch sensor in which the touch sensor is embedded in the display panel 170 is applied. By reducing the thickness of the display device 100 including the touch sensor, a thin and light display device 100 is provided. In detail, the separately manufactured touch sensor is not placed on the display panel in the embedded touch sensor, but the touch sensor is placed in the display panel. Therefore, the display device 100 has a small thickness and can be manufactured at low cost. In addition, in the display device 100, the touch sensor is placed in front of the touch sensitive element 160, thereby removing the damping phenomenon that the vibration transmitted to the user is reduced. Therefore, because the touch-sensitive element is driven according to a lower driving voltage, the power consumption of the touch-sensitive element 160 is also improved.

然而，隨著顯示面板與觸控感測器彼此整合，觸控敏感元件160需要被放置於顯示面板與觸控感測器上方或下方。當觸控敏感元件位於顯示面板與觸控感測器下方時，藉由使用者的手指與觸控敏感元件之間放置的顯示面板與觸控感測器減少振動。就是說，隨著使用者用手指觸碰的位置與觸控敏感元件間的距離增加，觸控敏感元件產生的振動的衰減程度也增加。因此，當觸控敏感元件被放置於顯示面板與觸控感測器下方時，只有透過施加高驅動電壓，具有足夠強度的振動才被傳送至使用者。因此，難以實施低功率消耗的觸控敏感元件。因此，在顯示裝置100中，觸控敏感元件160被放置於顯示面板170與觸控感測器上方。因此，與觸控敏感元件160被放置於顯示面板170與觸控感測器下方時相比，利用較低的功率消耗可傳送較強的振動至使用者。然而，由於施加至觸控敏感元件160的驅動電壓的緣故，觸控感測器可能故障，或者因為電活性聚合物製成的觸控敏感元件160具有非常高的驅動電壓，可能不會偵測到觸控輸入。因此，僅僅在未驅動觸控感測器的影像顯示週期中驅動顯示裝置100之觸控敏感元件160。就是說，在驅動觸控感測器的觸控感測週期期間，觸控敏感元件160的複數個電極161與162浮動，以最小化觸控敏感元件160產生的最小雜訊。另外，因為觸控敏感元件160被放置於最上部，可利用低功率消耗傳送觸覺回饋至使用者。However, as the display panel and the touch sensor are integrated with each other, the touch sensitive element 160 needs to be placed above or below the display panel and the touch sensor. When the touch sensitive element is located under the display panel and the touch sensor, the display panel and the touch sensor placed between the user's finger and the touch sensitive element reduce vibration. That is, as the distance between the position touched by the user's finger and the touch-sensitive element increases, the degree of attenuation of the vibration generated by the touch-sensitive element also increases. Therefore, when the touch-sensitive element is placed under the display panel and the touch sensor, only by applying a high driving voltage, vibrations with sufficient strength can be transmitted to the user. Therefore, it is difficult to implement a touch-sensitive element with low power consumption. Therefore, in the display device 100, the touch sensitive element 160 is placed above the display panel 170 and the touch sensor. Therefore, compared with when the touch-sensitive element 160 is placed under the display panel 170 and the touch sensor, it can transmit stronger vibration to the user with lower power consumption. However, due to the driving voltage applied to the touch-sensitive element 160, the touch sensor may malfunction, or because the touch-sensitive element 160 made of electroactive polymer has a very high driving voltage, it may not detect To touch input. Therefore, the touch sensitive element 160 of the display device 100 is driven only in the image display period when the touch sensor is not driven. That is, during the touch sensing period of driving the touch sensor, the plurality of electrodes 161 and 162 of the touch sensitive element 160 float to minimize the minimum noise generated by the touch sensitive element 160. In addition, since the touch-sensitive element 160 is placed on the uppermost part, it can transmit tactile feedback to the user with low power consumption.

如圖1至3所示，顯示面板170為平面模式的液晶顯示面板或者邊緣場切換模式的液晶顯示面板,，但是並非限制於此。或者，顯示面板170為扭轉向列（twisted nematic；TN）模式的液晶顯示面板或者垂直配向（vertical alignment；VA）模式的液晶面板。如上所述，利用垂直電場顯示影像的液晶顯示面板的情況下，共同電極123被放置於第二基板114上。As shown in FIGS. 1 to 3, the display panel 170 is a liquid crystal display panel in a flat mode or a liquid crystal display panel in a fringe field switching mode, but is not limited thereto. Alternatively, the display panel 170 is a liquid crystal display panel in a twisted nematic (TN) mode or a liquid crystal panel in a vertical alignment (VA) mode. As described above, in the case of a liquid crystal display panel that displays an image using a vertical electric field, the common electrode 123 is placed on the second substrate 114.

圖4A為剖面示意圖，表示當觸控敏感元件60之一個電極與複數個觸控電極30重疊時出現的比較例子之觸控輸入之錯誤識別的問題。圖4A中僅僅表示了蓋窗10、觸控敏感元件60之電極與複數個觸控電極30。圖4B為剖面示意圖，描述了第一代表性實施例之顯示裝置之功效，以及為了便於描述僅僅表示了顯示裝置100之蓋窗110、觸控敏感元件160與複數個觸控電極。FIG. 4A is a schematic cross-sectional view illustrating a problem of incorrect recognition of touch input in a comparative example when one electrode of the touch-sensitive element 60 overlaps with a plurality of touch electrodes 30. FIG. 4A only shows the cover window 10, the electrodes of the touch sensitive element 60, and the plurality of touch electrodes 30. FIG. 4B is a schematic cross-sectional view describing the functions of the display device of the first exemplary embodiment, and for convenience of description, only the cover window 110, the touch sensitive element 160, and the plurality of touch electrodes of the display device 100 are shown.

如圖4A之比較例子所示，當觸控敏感元件60之電極與複數個觸控電極30重疊時，則觸控輸入被錯誤識別。特別地，當觸控訊號藉由電壓源V僅僅被施加到複數個觸控電極30中的左觸控電極30時，因為電極浮動，所以全部電極由具有極性的電荷充電。因此，當使用者施加觸控輸入至蓋窗10時，與施加至觸控敏感元件60的電極的電荷一樣多的具有相反的極性電荷被施加至整個蓋窗10，甚至在未施加電壓的觸控電極30與觸控敏感元件60之電極之間形成電容C1與C2。因此，在這個比較例子中，甚至在未施加觸控訊號之觸控電極30對應的位置處電容改變，從而在未出現使用者的觸控輸入的位置處錯誤地判定使用者輸入。因此，無法準確地偵測使用者的觸控輸入的位置。As shown in the comparative example of FIG. 4A, when the electrodes of the touch-sensitive element 60 and the plurality of touch electrodes 30 overlap, the touch input is incorrectly recognized. In particular, when the touch signal is applied to the left touch electrode 30 of the plurality of touch electrodes 30 only by the voltage source V, because the electrodes float, all the electrodes are charged by a charge having a polarity. Therefore, when the user applies a touch input to the cover window 10, as many charges as the charges applied to the electrodes of the touch-sensitive element 60 have opposite polar charges to be applied to the entire cover window 10, even when the voltage is not applied. Capacitors C1 and C2 are formed between the control electrode 30 and the electrode of the touch-sensitive element 60. Therefore, in this comparative example, the capacitance is changed even at the position corresponding to the touch electrode 30 to which no touch signal is applied, so that the user input is erroneously determined at a position where the user's touch input does not occur. Therefore, the position of the user's touch input cannot be accurately detected.

相比而言，如圖4B所示，觸控敏感元件160之每一第一電極161與第二電極162的僅僅與顯示裝置100中的一個觸控電極130重疊。這種情況下，在觸控感測週期期間，當觸控訊號藉由電壓源V僅僅被施加至複數個觸控電極130中的左觸控電極時，因為觸控敏感元件160之第一電極161與第二電極162均浮動且第一電極161與第二電極162僅僅與一個觸控電極130重疊，具有極性之電荷例如被施加至觸控電極130之電荷僅僅被施加至複數個第一電極161中位於左側且對應左觸控電極130之第一電極161。因此，當使用者施加觸控輸入至蓋窗110時，與被施加至觸控敏感元件160之第一電極161的電荷對應的相反極性的電荷被施加至蓋窗110的對應區域。因此，在左觸控電極130與觸控敏感元件160之間產生電容C4，以及在觸控敏感元件160與蓋窗110之間產生電容C3，從而基於電容量的變化準確地偵測觸控位置。In contrast, as shown in FIG. 4B, each of the first electrode 161 and the second electrode 162 of the touch-sensitive element 160 overlaps only one touch electrode 130 in the display device 100. In this case, during the touch sensing period, when the touch signal is only applied to the left touch electrode of the plurality of touch electrodes 130 by the voltage source V, because the first electrode of the touch sensitive element 160 Both 161 and the second electrode 162 float and the first electrode 161 and the second electrode 162 overlap with only one touch electrode 130. A charge having a polarity, for example, a charge applied to the touch electrode 130 is applied only to a plurality of first electrodes. The first electrode 161 on the left side corresponding to the left touch electrode 130 in 161. Therefore, when a user applies a touch input to the cover window 110, a charge of an opposite polarity corresponding to the charge applied to the first electrode 161 of the touch sensitive element 160 is applied to a corresponding area of the cover window 110. Therefore, a capacitance C4 is generated between the left touch electrode 130 and the touch sensitive element 160, and a capacitance C3 is generated between the touch sensitive element 160 and the cover window 110, so that the touch position is accurately detected based on the change in the capacitance. .

圖5A至5C為平面示意圖，表示本揭露多個代表性實施例之顯示裝置之電極佈局結構。僅僅分別在觸控敏感元件560A、560B與560C之第一電極561A、561B與561C以及第二電極562A、562B與562C以及觸控電極530C之形狀與佈局方面，圖5A至5C分別表示的顯示裝置500A、500B與500C不同於結合圖1至3所描述的顯示裝置100。顯示裝置500A、500B與500C在其他部件方面實質上與顯示裝置100類似，因此可省略多餘的描述。圖5A至5C中，在從觸控敏感元件560A、560B與560C之頂部查看觸控敏感元件560A、560B與560C、觸控電極130與530C以及第一基板111的狀態下，為了便於描述，圖中僅僅表示觸控敏感元件560A、560B與560C、觸控電極130與530C以及顯示裝置100之第一基板111。因此，相同區域內其下放置的部件僅僅由參考標號表示。5A to 5C are schematic plan views showing electrode layout structures of a display device according to a plurality of representative embodiments of the disclosure. Only in terms of the shape and layout of the first electrodes 561A, 561B, and 561C, the second electrodes 562A, 562B, and 562C and the touch electrode 530C of the touch sensitive elements 560A, 560B, and 560C, respectively, the display devices shown in FIGS. 5A to 5C respectively 500A, 500B, and 500C are different from the display device 100 described in conjunction with FIGS. 1 to 3. The display devices 500A, 500B, and 500C are substantially similar to the display device 100 in other components, and thus redundant descriptions may be omitted. In FIGS. 5A to 5C, in a state where the touch sensitive elements 560A, 560B, and 560C, the touch electrodes 130 and 530C, and the first substrate 111 are viewed from the top of the touch sensitive elements 560A, 560B, and 560C, for convenience of description, FIG. Only the touch sensitive elements 560A, 560B, and 560C, the touch electrodes 130 and 530C, and the first substrate 111 of the display device 100 are shown in the figure. Therefore, the components placed underneath in the same area are indicated only by reference numerals.

如圖5A所示，觸控敏感元件560A之複數個電極561A與562A的每一個的尺寸小於對應的觸控電極130的尺寸。就是說，一個單元CE中放置的觸控敏感元件560A的第一電極561A與第二電極562A相對一個單元CE之第一電極561A與第二電極562A所面對的觸控電極130具有較小的尺寸，以及面對觸控電極130的第一電極561A的一個表面與第二電極562A的一個表面相對面對第一電極561A與第二電極562A的觸控電極130的另一表面具有較小的面積。因此，一個單元CE中的觸控電極130與鄰接單元CE中的第一電極561A及第二電極562A之間未產生電容。結果，更加準確地偵測使用者的觸控輸入。如圖5A所示，第一電極561A與第二電極562A具有相同的尺寸，但是本揭露並非限制於此，第一電極561A與第二電極562A可以尺寸不同。另外，第一電極561A與第二電極562A僅僅其中之一小於對應的觸控電極130，以及其他電極與觸控電極130具有相似的尺寸。As shown in FIG. 5A, the size of each of the plurality of electrodes 561A and 562A of the touch-sensitive element 560A is smaller than the size of the corresponding touch electrode 130. That is, the first electrode 561A and the second electrode 562A of the touch sensitive element 560A placed in one unit CE have a smaller size than the touch electrode 130 facing the first electrode 561A and the second electrode 562A of the unit CE. Size, and one surface of the first electrode 561A facing the touch electrode 130 and one surface of the second electrode 562A opposite to the other surface of the touch electrode 130 facing the first electrode 561A and the second electrode 562A have smaller area. Therefore, no capacitance is generated between the touch electrode 130 in one cell CE and the first electrode 561A and the second electrode 562A in the adjacent cell CE. As a result, the user's touch input is detected more accurately. As shown in FIG. 5A, the first electrode 561A and the second electrode 562A have the same size, but the disclosure is not limited thereto. The first electrode 561A and the second electrode 562A may have different sizes. In addition, only one of the first electrode 561A and the second electrode 562A is smaller than the corresponding touch electrode 130, and the other electrodes and the touch electrode 130 have similar dimensions.

如圖5B所示，觸控敏感元件560B的複數個電極561B與562B包含放置於電活性層163的相同表面上的複數個第一電極561B與複數個第二電極562B。就是說，第一電極561B與第二電極562B僅僅放置於電活性層163之一個表面上，從而在一個單元CE中彼此間隔開來。因此，各個觸控電極130與觸控敏感元件560B的兩個電極561B與562B重疊。另外，例如透過施加第一電壓在至第一電極561B且將第二電極562B接地，觸控敏感元件560B在第一電極561B與第二電極562B之間產生水平電場，從而透過施加水平電場而振動電活性層163。如圖5B所示的顯示裝置500B中，由透明導電材料製成的第一電極561B與第二電極562B被放置於電活性層163的一個表面上。因此，觸控敏感元件560B中光線入射所通過的電極的數目減少。因此，由於觸控敏感元件560B中的入射光線僅僅通過第一電極561B與第二電極562B其中之一，所以可提高觸控敏感元件560B的透射率。雖然圖5B中表示兩個觸控敏感元件560B的電極對應一個觸控電極130，本揭露並非限制於此，三個或多個觸控敏感元件560B的電極對應一個觸控電極130。As shown in FIG. 5B, the plurality of electrodes 561B and 562B of the touch-sensitive element 560B include a plurality of first electrodes 561B and a plurality of second electrodes 562B disposed on the same surface of the electroactive layer 163. That is, the first electrode 561B and the second electrode 562B are placed on only one surface of the electroactive layer 163 so as to be spaced apart from each other in one cell CE. Therefore, the two electrodes 561B and 562B of each touch electrode 130 and the touch sensitive element 560B overlap. In addition, for example, by applying a first voltage to the first electrode 561B and grounding the second electrode 562B, the touch sensitive element 560B generates a horizontal electric field between the first electrode 561B and the second electrode 562B, thereby vibrating by applying the horizontal electric field. Electroactive layer 163. In the display device 500B shown in FIG. 5B, a first electrode 561B and a second electrode 562B made of a transparent conductive material are placed on one surface of the electroactive layer 163. Therefore, the number of electrodes through which light is incident in the touch sensitive element 560B is reduced. Therefore, since the incident light in the touch sensitive element 560B passes through only one of the first electrode 561B and the second electrode 562B, the transmittance of the touch sensitive element 560B can be improved. Although FIG. 5B shows that the electrodes of the two touch sensitive elements 560B correspond to one touch electrode 130, the disclosure is not limited thereto, and the electrodes of the three or more touch sensitive elements 560B correspond to one touch electrode 130.

如圖5C所示，複數個觸控電極530C的每一個包含放置於一個單元CE中的第一觸控電極531C與第二觸控電極532C。第一觸控電極531C與第二觸控電極532C形成為梳狀，梳齒交替放置。這種情況下，觸控敏感元件560C之第一電極561C與第二電極562C被形成以分別與第一觸控電極531C與第二觸控電極532C重疊，且具有相同的尺寸。As shown in FIG. 5C, each of the plurality of touch electrodes 530C includes a first touch electrode 531C and a second touch electrode 532C placed in a unit CE. The first touch electrodes 531C and the second touch electrodes 532C are formed in a comb shape, and comb teeth are alternately placed. In this case, the first electrode 561C and the second electrode 562C of the touch-sensitive element 560C are formed to overlap the first touch electrode 531C and the second touch electrode 532C, respectively, and have the same size.

圖5A至5C分別表示的本揭露多個代表性實施例之顯示裝置500A、500B與500C中，當觸控敏感元件560A、560B與560C的複數個電極561A、562A、561B、562B、561C與562C的每一個僅僅與複數個觸控電極130與530C中的一個電極重疊時，對觸控敏感元件560A、560B與560C的複數個電極561A、562A、561B、562B、561C與562C的尺寸、形狀與佈局沒有限制。因此，複數個電極561A、562A、561B、562B、561C與562C的每一個僅僅與複數個觸控電極130與530C中的一個觸控電極重疊的範圍內，可任意地分別設計觸控敏感元件560A、560B與560C的複數個電極561A、562A、561B、562B、561C與562C。5A to 5C show the display devices 500A, 500B, and 500C of the representative embodiments of the present disclosure. When the touch sensitive elements 560A, 560B, and 560C have a plurality of electrodes 561A, 562A, 561B, 562B, 561C, and 562C, respectively, When each of the electrodes overlaps only one of the plurality of touch electrodes 130 and 530C, the size, shape, and shape of the plurality of electrodes 561A, 562A, 561B, 562B, 561C, and 562C of the touch-sensitive elements 560A, 560B, and 560C are different. There are no restrictions on the layout. Therefore, each of the plurality of electrodes 561A, 562A, 561B, 562B, 561C, and 562C only overlaps with one of the plurality of touch electrodes 130 and 530C, and the touch sensitive element 560A can be designed arbitrarily, respectively. Electrodes 561A, 562A, 561B, 562B, 561C and 562C.

為了便於描述，圖6A至6C中僅僅表示第一基板111以及顯示面板170之第一基板上放置的觸控電極130。圖6A中表示放置於第一基板111上的觸控電極130，具有寬度W1×寬度W2為4毫米×4毫米的尺寸，以及觸控電極130被放置為彼此分隔50微米的距離L。另外，觸控電極130由氧化銦錫(ITO)製成，且觸控電極130的厚度d1為500埃（Å）。For ease of description, only the first substrate 111 and the touch electrodes 130 placed on the first substrate of the display panel 170 are shown in FIGS. 6A to 6C. FIG. 6A shows that the touch electrodes 130 placed on the first substrate 111 have a width W1 × width W2 of 4 mm × 4 mm, and the touch electrodes 130 are placed at a distance L separated from each other by 50 micrometers. In addition, the touch electrode 130 is made of indium tin oxide (ITO), and the thickness d1 of the touch electrode 130 is 500 angstroms (Å).

圖6B係為沿6A所示顯示裝置之線A-A'之剖面示意圖，表示比較例子之觸控敏感元件60被放置於觸控電極130上且透過尖端680施加觸控輸入的情況。如圖6B所示，比較例子之觸控敏感元件60之電活性層63、第一電極61與第二電極62被放置為與全部觸控電極130重疊。比較例子之電活性層63由聚偏二氟乙烯（PVDF）製成且具有80微米的厚度d3。比較例子的第一電極61與第二電極62由氧化銦錫製成且具有500 Å的厚度d2。具有500微米厚度的玻璃紙帶（cellophane tape）690用於固定觸控敏感元件60。用於施加觸控輸入的尖端680由銅製成。尖端680的底部表面為平面，以及底部表面的直徑Ø為4毫米。FIG. 6B is a schematic cross-sectional view taken along line AA ′ of the display device shown in FIG. 6A, and shows a case where the touch sensitive element 60 of the comparative example is placed on the touch electrode 130 and a touch input is applied through the tip 680. As shown in FIG. 6B, the electroactive layer 63, the first electrode 61 and the second electrode 62 of the touch-sensitive element 60 of the comparative example are placed so as to overlap all the touch electrodes 130. The electroactive layer 63 of the comparative example is made of polyvinylidene fluoride (PVDF) and has a thickness d3 of 80 micrometers. The first electrode 61 and the second electrode 62 of the comparative example are made of indium tin oxide and have a thickness d2 of 500 Å. A cellophane tape 690 having a thickness of 500 micrometers is used to fix the touch sensitive element 60. The tip 680 for applying a touch input is made of copper. The bottom surface of the tip 680 is flat, and the diameter Ø of the bottom surface is 4 mm.

圖6C為沿圖6A所示顯示裝置之線A-A'之剖面示意圖，用於觸控輸入透過尖端680被施加至圖1與圖2所示本揭露之代表性實施例之顯示裝置100的情況。如圖6C所示，觸控敏感元件160的電活性層163與全部觸控電極130重疊，但是第一電極161與第二電極162的每一個被放置為僅僅與一個觸控電極130重疊。第一電極161與第二電極162的材料與厚度d2、電活性層163的材料與厚度d3、玻璃紙帶690以及尖端680與圖6B所示的比較例子相同。FIG. 6C is a schematic cross-sectional view taken along the line AA ′ of the display device shown in FIG. 6A. A touch input is applied to the display device 100 of the representative embodiment of the present disclosure shown in FIG. 1 and FIG. Happening. As shown in FIG. 6C, the electroactive layer 163 of the touch-sensitive element 160 overlaps all the touch electrodes 130, but each of the first electrode 161 and the second electrode 162 is placed to overlap only one touch electrode 130. The material and thickness d2 of the first electrode 161 and the second electrode 162, the material and thickness d3 of the electroactive layer 163, the cellophane tape 690, and the tip 680 are the same as the comparative example shown in FIG. 6B.

圖7A與7B係為使用圖6B與圖6C所示之排列比較與描述觸控訊號值測量結果之示意圖。圖7A表示依照圖6B之比較例子施加觸控輸入的情況下顯示面板170之區域所對應的觸控訊號值，以及圖7B表示依照圖6C所示之代表性實施例施加觸控輸入的情況下顯示面板170之區域所對應的觸控訊號值。圖7A與7B中的矩形單元的每一個表示觸控坐標，以及透過將每一觸控坐標的電容變化值轉換為數位資料值所獲得的矩形的圖形，即矩形中的圖形越大，對應位置處的電容變化量越大。7A and 7B are schematic diagrams for comparing and describing the measurement results of touch signal values using the arrangement shown in FIGS. 6B and 6C. FIG. 7A shows the touch signal value corresponding to the area of the display panel 170 in the case where a touch input is applied according to the comparative example of FIG. 6B, and FIG. 7B shows the case where the touch input is applied in accordance with the representative embodiment shown in FIG. 6C The touch signal value corresponding to the area of the display panel 170. Each of the rectangular units in FIGS. 7A and 7B represents touch coordinates, and a rectangular figure obtained by converting a capacitance change value of each touch coordinate into a digital data value, that is, the larger the figure in the rectangle, the corresponding position The greater the amount of change in capacitance at.

請參考圖6B與圖7A，比較例子中，觸控敏感元件60的第一電極與第二電極62被放置為與全部複數個觸控電極130重疊。因此，觸控輸入僅僅被施加至中央區域，但是周邊區域處的電容變化量也增加。因此，未出現使用者觸控輸入的周邊部中偵測到觸控。Please refer to FIG. 6B and FIG. 7A. In a comparative example, the first electrode and the second electrode 62 of the touch-sensitive element 60 are placed so as to overlap with all the plurality of touch electrodes 130. Therefore, the touch input is only applied to the central area, but the amount of capacitance change at the peripheral area also increases. Therefore, a touch is detected in the peripheral portion where the user's touch input does not occur.

請參考圖6C與7B，觸控敏感元件160之第一電極161與第二電極162的每一個僅僅與一個觸控電極130重疊。因此，僅僅實際觸碰的中央區域表現處大的電容變化量，以及周邊區域表現小的電容變化量。因此，僅僅使用者實際觸碰的區域被準確偵測為觸控輸入位置。Please refer to FIGS. 6C and 7B, each of the first electrode 161 and the second electrode 162 of the touch-sensitive element 160 overlaps only one touch electrode 130. Therefore, only the central area actually touched shows a large amount of capacitance change, and the peripheral area shows a small amount of capacitance change. Therefore, only the area actually touched by the user is accurately detected as the touch input position.

圖8為本揭露第二代表性實施例之顯示裝置之剖面示意圖。如圖8所示，顯示裝置800包含顯示面板870、觸控感測器與觸控敏感元件160。僅僅在顯示面板870為有機發光顯示面板且觸控感測器為外嵌式觸控感測器方面，圖8所示之顯示裝置800不同於結合圖1至3描述的顯示裝置100，以及顯示裝置100之驅動方法與顯示裝置800的驅動方法也不同。圖8所示之顯示裝置800的全部其他部件實質上與圖1至3所示之顯示裝置100類似，由此省略其多餘的描述。FIG. 8 is a schematic cross-sectional view of a display device according to a second exemplary embodiment of the disclosure. As shown in FIG. 8, the display device 800 includes a display panel 870, a touch sensor, and a touch sensitive element 160. The display device 800 shown in FIG. 8 is different from the display device 100 described in conjunction with FIGS. 1 to 3 only in that the display panel 870 is an organic light-emitting display panel and the touch sensor is an in-cell touch sensor. The driving method of the device 100 is also different from the driving method of the display device 800. All other components of the display device 800 shown in FIG. 8 are substantially similar to the display device 100 shown in FIGS. 1 to 3, and thus redundant descriptions are omitted.

如圖8所示，顯示面板870為頂部發射型有機發光顯示面板，其中有機發光元件820所發射的光線透過第二基板814被釋放。第二基板814與其上放置薄膜電晶體829之第一基板811相對。顯示面板870更包含第一絕緣層812、第二絕緣層813、過塗佈層819、護堤817以及封裝部818。As shown in FIG. 8, the display panel 870 is a top emission type organic light emitting display panel, in which light emitted by the organic light emitting element 820 is released through the second substrate 814. The second substrate 814 is opposite to the first substrate 811 on which the thin film transistor 829 is placed. The display panel 870 further includes a first insulating layer 812, a second insulating layer 813, an overcoat layer 819, a bank 817, and a packaging portion 818.

第一基板811支撐顯示面板870之多個部件，以及由撓性玻璃或塑膠製成。The first substrate 811 supports various components of the display panel 870 and is made of flexible glass or plastic.

薄膜電晶體829被放置於第一基板811上。在薄膜電晶體中，主動層被放置於第一基板811上，以及用於絕緣主動層與閘極之第一絕緣層812被放置於主動層上。第二絕緣層被放置於第一絕緣層812與閘極上且覆蓋閘極。源極與汲極被放置於第二絕緣層813上且電連接主動層。為了便於描述，如圖8所示，顯示裝置800中僅僅包含一個驅動薄膜電晶體，但是本揭露並非限制於此，顯示裝置800中還可以包含切換薄膜電晶體、電容器等。另外，圖8所示的薄膜電晶體829表示為具有共面結構，但是本揭露並非限制於此，還可以使用具有交錯結構之薄膜電晶體。The thin film transistor 829 is placed on the first substrate 811. In the thin film transistor, an active layer is placed on the first substrate 811, and a first insulating layer 812 for insulating the active layer and the gate is placed on the active layer. The second insulating layer is placed on the first insulating layer 812 and the gate electrode and covers the gate electrode. The source and the drain are placed on the second insulating layer 813 and are electrically connected to the active layer. For ease of description, as shown in FIG. 8, the display device 800 includes only one driving thin film transistor, but the disclosure is not limited thereto. The display device 800 may also include a switching thin film transistor, a capacitor, and the like. In addition, the thin film transistor 829 shown in FIG. 8 is shown as having a coplanar structure, but the disclosure is not limited thereto, and a thin film transistor having a staggered structure may also be used.

過塗佈層819形成於薄膜電晶體829上，這個層將薄膜電晶體829的頂部平面化。過塗佈層819由有機絕緣材料例如丙烯酸基樹脂製成。An overcoat layer 819 is formed on the thin film transistor 829, and this layer planarizes the top of the thin film transistor 829. The overcoat layer 819 is made of an organic insulating material such as an acrylic-based resin.

有機發光元件820被放置於過塗佈層819上，且包含陽極821、有機層822與陰極823。陽極821被放置於過塗佈層819上，且透過過塗佈層819的接觸孔電連接薄膜電晶體829之源極與汲極其中之一。因為顯示面板870為頂部發射型有機發光顯示面板，陽極821包含由透明導電材料製成的透明導電層，以及所以放置於透明導電層下方具有極佳反射率的金屬材料製成的反射層。然而，陽極821的層積結構並非限制於此。護堤817被放置為覆蓋陽極821兩端。未被護堤817覆蓋的陽極821的區域被定義為發射區域。有機層822被放置於陽極821與護堤817上。舉個例子，有機層822具有電洞注入層(HIL)、電洞傳輸層(HTL)、有機發射層(EML)、電子傳輸層(ETL)與電子注入層(EIL)順序沈積之結構。另外，有機層822具有其中複數個發光單元各自包含層積的有機發射層的結構，此外，有機層822如圖8所示形成於陽極821與護堤817上。然而，有機層822僅僅形成於護堤817所暴露的陽極821上。陰極823被放置於有機層822上。陰極823由非常小厚度的金屬材料製成或者由透明導電材料製成，因為顯示面板870為頂部發射型有機發光顯示面板，但是並非限制於此。The organic light emitting element 820 is placed on the overcoat layer 819 and includes an anode 821, an organic layer 822, and a cathode 823. The anode 821 is placed on the overcoat layer 819, and one of the source and the drain of the thin film transistor 829 is electrically connected through the contact hole of the overcoat layer 819. Because the display panel 870 is a top-emission organic light-emitting display panel, the anode 821 includes a transparent conductive layer made of a transparent conductive material, and a reflective layer made of a metal material having an excellent reflectance placed under the transparent conductive layer. However, the laminated structure of the anode 821 is not limited to this. The berm 817 is placed so as to cover both ends of the anode 821. The area of the anode 821 not covered by the berm 817 is defined as the emission area. The organic layer 822 is placed on the anode 821 and the bank 817. For example, the organic layer 822 has a structure in which a hole injection layer (HIL), a hole transport layer (HTL), an organic emission layer (EML), an electron transport layer (ETL), and an electron injection layer (EIL) are sequentially deposited. In addition, the organic layer 822 has a structure in which a plurality of light-emitting units each include a laminated organic emission layer, and the organic layer 822 is formed on the anode 821 and the bank 817 as shown in FIG. 8. However, the organic layer 822 is formed only on the anode 821 exposed by the berm 817. The cathode 823 is placed on the organic layer 822. The cathode 823 is made of a metal material with a very small thickness or made of a transparent conductive material because the display panel 870 is a top emission organic light emitting display panel, but it is not limited thereto.

第二基板814被放置於有機發光元件820上，以及封裝部818被放置於有機發光元件820與第二基板814之間。第二基板814被放置為面對第一基板811且由撓性玻璃或塑膠製成。封裝部818保護有機發光元件820避免水或氧氣滲透，為無機層或者具有無機層與有機層822交替層積之結構。或者，封裝部818由面密封材料製成。The second substrate 814 is placed on the organic light emitting element 820, and the package portion 818 is placed between the organic light emitting element 820 and the second substrate 814. The second substrate 814 is placed to face the first substrate 811 and is made of flexible glass or plastic. The encapsulation portion 818 protects the organic light emitting element 820 from water or oxygen, and has an inorganic layer or a structure in which an inorganic layer and an organic layer 822 are alternately laminated. Alternatively, the package portion 818 is made of a face sealing material.

與顯示面板870整合的觸控感測器為外嵌觸控感測器式。就是說，觸控感測器形成於顯示面板870上方。舉個例子，如圖8所示，觸控感測器之觸控電極830被放置於第二基板814之頂部表面上，第二基板814係為顯示面板870之上基板。觸控電極830透過濺射等利用透明導電材料形成於第二基板814之頂部表面上。The touch sensor integrated with the display panel 870 is an external touch sensor type. That is, the touch sensor is formed above the display panel 870. For example, as shown in FIG. 8, the touch electrode 830 of the touch sensor is placed on the top surface of the second substrate 814, which is a substrate above the display panel 870. The touch electrode 830 is formed on the top surface of the second substrate 814 by using a transparent conductive material through sputtering or the like.

進一步如圖8所示，觸控敏感元件160被放置於顯示面板870與觸控感測器上，以及蓋窗110被放置於觸控敏感元件160上。觸控敏感元件160透過第一黏合層815與第二基板814黏合以及透過第二黏合層116與蓋窗110黏合。As further shown in FIG. 8, the touch sensitive element 160 is placed on the display panel 870 and the touch sensor, and the cover window 110 is placed on the touch sensitive element 160. The touch-sensitive element 160 is adhered to the second substrate 814 through the first adhesive layer 815 and is adhered to the cover window 110 through the second adhesive layer 116.

與本揭露第一代表性實施例之顯示裝置100類似，本揭露第二代表性實施例之顯示裝置800還包含觸控敏感元件160之複數個電極161與162，複數個電極161與162的每一個僅僅與複數個觸控電極830之一個觸控電極830重疊。因此，可抑制第一電極161及第二電極162與複數個觸控電極830之重疊，從而避免觸控輸入之錯誤識別。Similar to the display device 100 of the first exemplary embodiment of the present disclosure, the display device 800 of the second exemplary embodiment of the present disclosure further includes a plurality of electrodes 161 and 162 of the touch sensitive element 160, each of the plurality of electrodes 161 and 162 One overlaps only one touch electrode 830 of the plurality of touch electrodes 830. Therefore, the overlap of the first electrode 161 and the second electrode 162 with the plurality of touch electrodes 830 can be suppressed, thereby avoiding the incorrect recognition of the touch input.

因為顯示裝置800包含外嵌式觸控感測器，所以觸控電極830未放置於顯示面板870中。就是說，觸控電極830未作業為有機發光源極820之陽極821或陰極823。因此，在驅動顯示裝置800時，可同時完成影像顯示週期與觸控感測週期。然而，在顯示裝置100中，顯示裝置800之觸控敏感元件160需要被時分驅動為觸控感測週期與觸控敏感元件驅動週期。就是說，當觸控敏感元件160為觸控感測週期內，因為在觸控感測週期期間，觸控訊號透過觸控電極830被施加至觸控電極830用於觸控偵測，所以觸控感測器不會正常地偵測觸控輸入。因此，在觸控感測週期期間，觸控敏感元件160的複數個電極浮動，這樣觸控感測器可準確地偵測使用者的觸控輸入。Because the display device 800 includes an in-cell touch sensor, the touch electrodes 830 are not placed in the display panel 870. That is, the touch electrode 830 is not operated as the anode 821 or the cathode 823 of the organic light emitting source 820. Therefore, when the display device 800 is driven, the image display period and the touch sensing period can be completed at the same time. However, in the display device 100, the touch sensitive element 160 of the display device 800 needs to be time-divisionally driven into a touch sensing period and a touch sensitive element driving period. That is, when the touch sensing element 160 is in the touch sensing period, since the touch signal is applied to the touch electrode 830 for touch detection through the touch electrode 830 during the touch sensing period, the touch The touch sensor does not detect touch input normally. Therefore, during the touch sensing cycle, the plurality of electrodes of the touch sensitive element 160 float, so that the touch sensor can accurately detect the user's touch input.

在觸控敏感元件驅動週期期間，未驅動觸控感測器，觸控敏感元件驅動訊號被施加至觸控敏感元件160以驅動觸控敏感元件160。舉個例子，在觸控敏感元件件驅動週期期間，交流電壓或脈衝電壓被施加至觸控敏感元件160之第一電極161，觸控敏感元件160之第二電極162接地以振動電活性層163。During the touch-sensitive element driving cycle, the touch sensor is not driven, and the touch-sensitive element driving signal is applied to the touch-sensitive element 160 to drive the touch-sensitive element 160. For example, during the driving period of the touch sensitive element, an AC voltage or a pulse voltage is applied to the first electrode 161 of the touch sensitive element 160, and the second electrode 162 of the touch sensitive element 160 is grounded to vibrate the electroactive layer 163 .

一些代表性實施例中，顯示面板870為底部發射型有機發光顯示面板。這種情況下，觸控電極830被放置於第一電極811之底部表面上，以及觸控敏感元件160被放置於觸控電極830下方。In some representative embodiments, the display panel 870 is a bottom emission organic light emitting display panel. In this case, the touch electrode 830 is placed on the bottom surface of the first electrode 811, and the touch sensitive element 160 is placed below the touch electrode 830.
